Getting Started - A Step-by-Step Guide

Offer readers a practical guide on getting started with Amazon Managed Service for Prometheus. Cover the essential steps, share best practices, and highlight any considerations for a smooth onboarding process.

Step 1: Accessing the AWS Management Console
Begin by logging into the AWS Management Console. Navigate to the Amazon Managed Service for Prometheus section and initiate the setup process.

Step 2: Creating a Prometheus Workspace
Follow the prompts to create a new Prometheus workspace. Define the required parameters such as the workspace name, desired region, and any specific configurations based on your monitoring needs.

arn:aws:aps:us-east-1:726459634338:workspace/ws-420cc8c0-93ff-4bfd-9dfb-48e0e9a02d5a

Endpoint - remote write URL
https://aps-workspaces.us-east-1.amazonaws.com/workspaces/ws-420cc8c0-93ff-4bfd-9dfb-48e0e9a02d5a/api/v1/remote_write

Endpoint - query URL
https://aps-workspaces.us-east-1.amazonaws.com/workspaces/ws-420cc8c0-93ff-4bfd-9dfb-48e0e9a02d5a/api/v1/query

Step 3: Set up IAM roles for service accounts
For the method of onboarding that we are documenting, you need to use IAM roles for service accounts in the Amazon EKS cluster where the Prometheus server is running. These roles are also called service roles.

With service roles, you can associate an IAM role with a Kubernetes service account. This service account can then provide AWS permissions to the containers in any pod that uses that service account. For more information, see IAM roles for service accounts.

If you have not already set up these roles, follow this instructions to set up the roles: Set up service roles for the ingestion of metrics from Amazon EKS clusters.

Please make sure you have created an IAM role called amp-iamproxy-ingest-role before continuing.

Step 4: Upgrade your existing Prometheus server using Helm (for Prometheus version 2.26.0 or later)

The instructions in this section includes setting up remote write and sigv4 to authenticate and authorize the Prometheus server to remote write to your AMP workspace.

To set up remote write from a Prometheus server using Helm chart:
Create a new remote write section in your Helm configuration file:

serviceAccounts:
    server:
        name: "amp-iamproxy-ingest-service-account"
        annotations:
            eks.amazonaws.com/role-arn: "arn:aws:iam::726459634338:role/amp-iamproxy-ingest-role"
server:
    remoteWrite:
        - url: https://aps-workspaces.us-east-1.amazonaws.com/workspaces/ws-420cc8c0-93ff-4bfd-9dfb-48e0e9a02d5a/api/v1/remote_write
          sigv4:
            region: us-east-1
          queue_config:
            max_samples_per_send: 1000
            max_shards: 200
            capacity: 2500

Update your existing Prometheus Server configuration using Helm:

First, find your Helm chart name by entering the following command:

helm ls --all-namespaces

In the output from this command, look for a chart with a name that includes "prometheus".

Then enter the following command:

helm upgrade prometheus-chart-name prometheus-community/prometheus -n prometheus_namespace -f my_prometheus_values_yaml --version current_helm_chart_version

Replace these placeholders with the following:

• Replace prometheus-chart-name with the name of the helm chart you found with the previous command.
• Replace prometheus_namespace with the name of the Kubernetes namespace where your Prometheus Server is installed.
• Replace my_prometheus_values_yaml with the path to your Helm configuration file.
• Replace current_helm_chart_version with the current version of the Prometheus Server Helm chart you found with the previous command.

Grafana

Step-1: Follow the following procedure to setting up managed grafana.

Step 2: Configuring Data Retention and Storage Options
Fine-tune your monitoring environment by configuring data retention policies and storage options. Tailor these settings to align with your application's requirements and expected data volumes.

Step 3: Integrating with AWS Resources
Connect Amazon Managed Service for Prometheus with your existing AWS resources. This could include linking it to Amazon Elastic Kubernetes Service (EKS) clusters, Amazon EC2 instances, or any other AWS services generating monitoring data.

Step 4: Setting Up Alerts and Notifications
Enhance your observability by configuring alerts and notifications. Define thresholds for metrics that matter most to your applications and establish alerting mechanisms to keep your team informed of any deviations from expected behavior.

Step 5: Exploring Querying Capabilities
Dive into the querying capabilities of Amazon Managed Service for Prometheus. Learn how to write PromQL queries to extract valuable insights from your monitoring data. Leverage this functionality to troubleshoot issues, analyze trends, and optimize performance.

Step 6: Integrating with AWS CloudWatch
Explore the seamless integration between Amazon Managed Service for Prometheus and AWS CloudWatch. Understand how these services work together to provide a comprehensive monitoring solution for your AWS environment.

Step 7: Scaling and Optimization
As your application grows, ensure that your monitoring solution scales accordingly. Learn best practices for scaling Amazon Managed Service for Prometheus and optimizing its performance to meet the evolving demands of your applications.

Wrap up the blog by summarizing the key takeaways and emphasizing the transformative potential of Amazon Managed Service for Prometheus.
